The 45 degree corner bracket connects two aluminum profiles at 45 degrees. In practical work, aluminum profiles are generally connected at 90 degrees. This connection method is simple and convenient to operate and the work progress is fast. 45 degree angle code is generally used in load-bearing parts.

Two 45 degree corner bracket are installed at both ends of a section of aluminum profile, and then installed between two aluminum profiles with an included angle of 90 degrees to form a triangle. This improves the load-bearing strength of the aluminum profile.
